Schneider 140CPU11303 Seven common problems of the CPU module

• Schneider 140CPU11303 FAQs

　　Question 1:Is it easy to report insufficient memory when using IEC programming for 140CPU11303?

　　Solution:140CPU11303 corresponds to two firmware:one corresponds to 140CPU11303,and one corresponds to 140CPU11303S.When the corresponding 140CPU11,303 firmware is used,the CPU supports both LL984 and IEC,but the IEC capacity will be small.If you are sure that your application is entirely IEC application,please update the CPU firmware to 140CPU11303S firmware.After this operation,the CPU IEC programming capacity will be greatly expanded.Specific operations:The Quantum 11303 firmware is updated to support only IEC programming;In Concept software,change the CPU model from 140CPU11303 to 140CPU11303S.

　　Problem 2:Brush the 140CPU11303 PV06 firmware to 140CPU11303S,download the program,and it runs normally,but power is supplied again after power failure.The Run light is off,and the IO module Active light is off.The CPU cannot be started,and an error 0004 is reported.After downloading the program again,it is OK

　　Solution:The 140CPU11303 firmware is updated to 140CPU11303S,the program is downloaded,the CPU is started and running normally,and the CPU is powered back after power failure.The normal situation is what state the CPU was in before power failure and what state it is still in after power failure.The phenomenon described in the title is obviously abnormal.We perform the same operation on another new 140CPU11303 PV06 CPU as described in the title,The fault phenomenon described in the title is not reproduced,and it is judged that the fault phenomenon is an individual fault rather than a batch fault.It has nothing to do with the upgrade of the 140CPU11303 hardware version to PV06 and the firmware update file bug corresponding to PV06.In addition,when the CPU is shut down,the Active light on all IO modules is off,which is a normal phenomenon.

　　Problem 3:140CPU11303 reported an error when downloading the program,and the displayed error code is"OLI-21707".However,if only the configuration is changed,other programs remain unchanged,and then downloaded to 140CPU43412A,everything is normal

　　Solution:The reason for the above error is that the user programmed Project contains EFBs involving floating point operations.For 140CPU43412A,it can support floating point operations without any processing.For 140CPU11303,if it does not do any processing,it does not support floating point operations.Therefore,if the corresponding loadable file is not downloaded before the program is downloaded,an error will always be reported when downloading the project to 140CPU11303,However,when downloaded to 140CPU43412A,everything will be normal The solution is to download the loadable file named"EMUQ"before downloading the program.

　　Problem 4:The power supply of the 140CPU11303 device is restored after power failure,and the CPU cannot start automatically.How to solve this problem

　　Solution:After the 140CPU11303 equipment is powered off,the CPU will be restored to the state before the equipment is powered off,and the 140CPU43412A/53414A cannot be configured with software to restore the state after the equipment is powered on.If the CPU state is run before the power failure and stop after the power supply is restored,it is highly suspected that the device failure will cause the CPU to fail to start.

　　Question 5:What are the functions of ASCII/RTU/MEM dial codes on the front panel of Concept Quantum CPU

　　The setting of relevant parameters of 140CPU11303 MB is based on the setting position of the"Modbus"setting switch on the CPU module,as shown in the following figure:

　　If the"Modbus"setting switch is set to the"ASCII"position,the parameter Settings are as follows:

　　If the"Modbus"setting switch is set to the"RTU"position,the parameter Settings are as follows:

　　If the Modbus Settings switch is set to the MEM position,the parameters are set as follows:

　　Q6:When the Quantum series CPU is powered down,what is the maximum storage period of memory data through the battery?

140CPU11302   454 days

140CPU11303   238 days

140CPU43412X 238 days

140CPU53414X 119 days

　　Q7:What are the main frequencies of Quantum and Premium processors?

　　Quantum Series:

    Premium Series:
